REBOL PARSE RULE PARSER

1. What is this all about?

Parse and analyse REBOL Parse Rules.

There is more documentation within the comments of the script.

2. How do you use the functions?

  • The script starts by calling a function I have set in my REBOL environment called SCRIPT-MANAGER. Here's a simplified stand-in for that function you can use - just put it in your calling script:
        if not value? 'script-manager [
            script-manager: func ['word /local needs][
                if any [
                    :word <> 'do-needs
                    none? in system/script/header 'needs
                    none? needs: system/script/header/needs
                ][return]
                if not parse needs: compose [(:needs)] [some file!][make error! {Expected a NEEDS block consisting of file!.}]
                foreach [file] needs [do file]
            ]
        ]
  • You will need each of the scripts listed in the NEEDS block in the same directory.
